backup delay
backup delay
To specify how long a backup pseudowire (PW) virtual circuit (VC) should wait before resuming
operation after the primary PW VC goes down, use the backup delay command in interface
configuration mode or xconnect configuration mode. To return to the default so that as soon as the
primary fails, the secondary is immediately brought up without delay, use the no form of this command.
backup delay enable-delay {disable-delay | never}
no backup delay enable-delay {disable-delay | never}
Syntax Description
Command Default If a failover occurs, the xconnect redundancy algorithm immediately switches over or falls back to the
backup or primary member in the redundancy group.
Command Modes Interface configuration
Xconnect configuration
Command History
Examples The following example shows a Multiprotocol Label Switching (MPLS) xconnect with one redundant
peer. After a switchover to the secondary VC occurs, there is no fallback to the primary VC unless the
secondary VC fails.
Router# config t
Router(config)# pseudowire-class mpls
Router(config-pw-class)# encapsulation mpls
Router(config-pw-class)# exit
Router(config)# interface atm1/0
Router(config-if)# xconnect 10.0.0.1 50 pw-class mpls
enable-delay Number of seconds that elapse after the primary PW VC goes down before the
Cisco IOS software activates the secondary PW VC. The range is 0 to 180.
The default is 0.
disable-delay Number of seconds that elapse after the primary PW VC comes up before the
Cisco IOS software deactivates the secondary PW VC. The range is 0 to 180.
The default is 0.

PW VC becomes available again, unless the secondary PW VC fails.
